by Texas Instruments

Published on June 09, 2008

Overview

In this activity, the average rate of change between two points is defined and then used as a concept connecting ideas of slope, difference quotients, and approximations of instantaneous rate of change.

Key Steps

  • Image

    Students will explore a graph by tracing, finding intercepts, and zooming in order to find the average rate of change. 

  • Image

    Students will use an algebraic approach to find average rate of change.
